Amathinidae, is a taxonomic family mostly consisting of small and minute sea snails, marine heterobranch gastropod molluscs or micromolluscs in the superfamily Pyramidelloidea.


Together with Pyramidellidae, Ebalidae, Turbonillidae, Odostomidae and other genera they form the superfamily Pyramidelloidea.

Little is known on the biology of the group, but some data on the anatomy and systematic position is given by Ponder (1987) and Huber (1993).
